Earthborn Backgrounds
Scope
This file owns the Game 1 Earthborn condition: the MC originates on Earth and carries Earth-born knowledge into Valenar. It records what that origin changes locally: recognition, analogy, adaptation, cross-domain learning, and early problem framing. It does not own the exact background-selection roster, opening kit tables, or a special Earth gear system. Those are game-design or content surfaces. This file also records the hard boundary that Earth tools remain mundane under the True Harm rule.
Facts
Fact: The MC's origin is Earth
The MC is a mundane human from our world. They are not native to the Valenar
setting; they have no childhood memory of the continent, no native cultural
context, and no clean divine mark. Their arrival in the Zone is explained by
the Corebound origin (see gl-mc-corebound.md); their first interpretive frame
for danger, work, tools, and comparison is Earth-born experience.

Fact: The player chooses an Earthborn background, but the lasting consequence is recognition bias rather than class lock-in
At character creation the player chooses the MC's Earth-born background. The lasting consequence is a bias in what the MC notices first, learns faster, trusts under pressure, and can explain by analogy. The background is not a class tree, not a fixed late-game identity, and not a roster-owned job slot.

Exposure note: Surfaced as revealed per lh-game1-world-hooks.md — background selection is a character-creation surface.
Fact: Earthborn strength is broad learning, cross-domain transfer, and rapid pattern acquisition
Earth-born knowledge gives the MC a faster route from observation to working theory. The advantage is not one special power; it is a quicker ability to recognize patterns, improvise, compare unlike problems, and carry one kind of learning into another. The MC becomes dangerous by adapting and learning, not by unfolding a preloaded hero package.

Fact: Earthborn backgrounds bias recognition and early learning across many surfaces
An Earthborn background can change how quickly the MC recognizes field risk, reads a ruin, improvises camp work, parses old records, triages injuries, tests materials, or notices that one pattern resembles another. The result is faster pattern acquisition and better grounded adaptation across survival, craft, investigation, and interpretation.

Fact: This file does not own a fixed background roster or a dedicated Earth gear system
The exact selectable background menu, opening kit, and any UI-facing loadout tables belong to game-design and content owners, not to this lore page. The local truth this file commits is the Earthborn condition and its consequences, not a numbered roster or a separate Earth-only equipment track.

Fact: Earth-derived tools follow the True Harm rule
Mundane Earth-derived tools — knives, improvised implements, treated materials,
field gear, and anything else the MC can reproduce through ordinary means —
remain mundane under ud-world-law.md. They disperse demons but do not
destroy demon essence. Earthborn knowledge does not grant a bypass to True
Harm.

Exposure note: Surfaced as revealed per lh-game1-world-hooks.md — the player discovers through play that Earth tools fail to destroy demons.
Fact: Earth knowledge can accelerate discovery of True Harm categories without bypassing them
Earth-born habits of comparison, record-keeping, testing, field inference, and cross-domain transfer can help the MC recognize, reconstruct, or adapt True Harm categories faster than a setting-native might. The underlying world-law categories still apply. Earth cleverness accelerates recognition and learning; it does not replace the categories themselves.

Fact: The MC's individual knowledge is the resource, not an imported industrial base
Earthborn backgrounds do not smuggle an industrial economy into Game 1. The resource is the MC's individual knowledge, hand-tool competence, and ability to adapt under local constraints. There are no factories, no mass production lines, no electrical grids, and no imported supply chains waiting offscreen. What matters is what one displaced person can learn, test, and build inside the setting's actual material limits.
